1. Field of the Invention
The present invention relates to an electronic endoscope having a treatment appliance insertion port and various operation switches formed in and on an operation unit thereof, and having a universal cord extended from the operation unit.
2. Description of the Related Art
In recent years, endoscopes having an elongated insertion unit inserted into a body cavity and having, if necessary, a treatment appliance passed through a treatment appliance channel so as to enable various kinds of examinations and treatments have widely been adopted. The endoscopes include an electronic endoscope having a solidstate imaging device such as a charge-coupled device (CCD) incorporated as an imaging means therein. The electronic endoscope converts an optical image of an object converged on the CCD into an electric signal and the electric signal into an image signal, displays an image of the object on the screen of a monitor, and thus enables observation of a lesion or the like.
A type of electronic endoscope has a soft insertion unit that includes a bending portion formed by concatenating a plurality of bending pieces. The bending portion can be angled vertically and laterally. The insertion unit can therefore be inserted into a tortuous body cavity through the oral cavity or anus. Angling the bending portion is controlled using an angling knob that is one of operation switches formed on an operation unit communicating with the proximal end of the insertion unit and filling the role of a hand-held unit.
Moreover, a universal cord accommodating a signal cable extended from the CCD or operation switch and a light guide fiber bundle is extended from a flank of the operation unit. A connector is attached to one end of the universal cord. Consequently, the universal cord is coupled to a camera control unit (hereinafter a CCU) that is an external apparatus through the connector so that the universal cord can be uncoupled freely.
The CCU has a light source and a signal processor, which are not shown, incorporated therein. The light source supplies illumination light to the electronic endoscope. The signal processor processes an electric signal photoelectrically converted from an optical image of an object by the solid-state imaging device incorporated in the distal part of the insertion unit. When the universal cord is coupled to the CCU through the connector, it becomes possible to transfer the electric signal or supply illumination light.
As shown in
The operation unit 100 is designed to be preferably held with the left hand. A user holds the middle portion, which is not shown, of the insertion unit 111 with his/her right hand. The user introduces the distal part of the insertion unit 111 to a region to be observed in a body cavity while handling the angling knobs 105 and 106 with the fingers of his/her left hand. Otherwise, a user holds the insertion unit 111 with his/her right hand, and handles the suction button 103, aeration/perfusion button 104, and various control switches 107, 108, 109, and 110 with his/her left hand.
A user can handle the operation switches with the fingers of his/her left hand without parting his/her right hand from the insertion unit 111. The user can efficiently introduce the insertion unit 111 to a region to be observed. Moreover, since it is unnecessary to handle the various operation switches on the operator portion 102 with the wet right hand, the insertion unit 111 remains sanitary.
However, as shown in
A discussion will be made of a case where a connector 113 attached to the proximal end of the universal cord 111 as shown in FIG. 3A and
For example, assume that the CCU 114 is, as shown in
Furthermore, when an attempt is made to handle any of the various control switches 107, 108, 109, and 110, aeration/perfusion button 104, suction button 103, and angling knobs 105 and 106 formed on the operation unit 100, a force with which the hand-held portion 101 is held may be gone. This poses a problem in that the held state of the operation unit 100 can become unstable.
A treatment appliance insertion port 117 (see
In efforts to improve maneuverability of an endoscope, various proposals have been disclosed in, for example, Japanese Unexamined Patent Application Publication Nos. 8-19507 and 7-100105, Japanese Unexamined Utility Model Publication No. 60-171403, and Japanese Examined Utility Model Publication No. 63-23042.
Accordingly, an object of the present invention is to provide an electronic endoscope having the characteristics of a stable hold, excellent user-friendliness, and superb maneuverability.
Briefly, an electronic endoscope in accordance with the present invention consists broadly of an operation unit, an elongated insertion unit, and a universal cord. The operation unit has a treatment appliance insertion port and various operation switches and fills the role of a hand-held unit. The insertion unit extends from the lower end of the operation unit in a direction substantially corresponding to the longitudinal direction of the operation unit. The universal cord extends from an upper part of the operation unit in a direction crossing the longitudinal direction of the operation unit at an acute angle, and accommodates at least a signal cable.
FIG. 3A and
FIG. 5A and
FIG. 6A and
FIG. 10A and
FIG. 11A and
Referring to the drawings, embodiments of the present invention will be described below.
The first embodiment of the present invention will be described with reference to
An electronic endoscope (hereinafter simply an endoscope) 1 in accordance with the present embodiment shown in
The insertion unit 2 is extended from the distal end of the operation unit 3 in a direction substantially corresponding to the longitudinal direction of the operation unit 3. The insertion unit 2 has a rigid distal part 21, a bending portion 22, and a flexible tube 23 arranged in that order from the distal end thereof. The distal part 21 has a built-in imaging device that is not shown. The bending portion 22 has a plurality of bending pieces concatenated and can be angled vertically and laterally. The flexible tube 23 has flexibility.
The operation unit 3 consists of a hand-held portion 3a to be held by an operator and an operator portion 3b located proximally to the hand-held portion 3a (upside in the drawing). The operator portion 3b has operation switches formed thereon in a watertight fashion. The operation switches include an angling knob 31 used to angle the bending portion 22, pushbutton switches such as a suction button 32 and an aeration/perfusion button 33, and control switches 34, 35, and 36 used to control display of an endoscopic image on a display device that is not shown.
A treatment appliance insertion port 37 through which a treatment appliance such as forceps is introduced into a body cavity over a suction channel is formed between the aeration/perfusion button 33 and suction button 32.
Moreover, a cord juncture 38 at which the universal cord 4 is coupled and fixed to the operation unit 3 is projected from one flank of the operation unit 3. The cord juncture 38 meets the operation unit 3 at an acute angle (θ) with respect to the longitudinal direction of the operation unit 3.
A crossed-axes angle θ1 shall be, as shown in
Consequently, the insertion unit 2 and universal cord 4 are extended downwards in
An operator's left hand with which the operation unit 3 is held is rested on part of one flank of the operation unit 3 between the operation unit 3 and the cord juncture 38 and a coupling fixture 40 attached to an end of the universal cord 4. The cord juncture 38 and coupling fixture 40 therefore traverses the back of the operator's left hand. According to the present embodiment, the cord juncture 38 and coupling fixture 40 constitute a hold assistant against which the operator's left hand is rested.
The coupling fixture 40 attached to one end of the universal cord 4 serves as an integral part of not only the hold assistant but also a cord twist correcting means. The coupling fixture 40 is joined to the cord juncture 38 formed on the operation unit 3, whereby the universal cord 4 can be rotated 180°C or more as mentioned later. Moreover, a connector 4a is attached to the other end of the universal cord 4. The connector 4a is coupled to a camera control unit 5 (see
A signal line and a light guide fiber bundle or the like are passed through the universal cord 4, operation unit 3, and insertion unit 2. The signal line links an imaging device that is not shown and the CCU 5. Illumination light emanating from a light source, which is not shown, incorporated in the CCU 5 is propagated to the distal part 21 of the insertion unit 2 over the light guide fiber bundle. Moreover, anti-break members 6a and 6b are used to protect the insertion unit 2 and universal cord 4 respectively from buckling.
Referring to FIG. 5A and
As shown in
As shown in FIG. 5A and
The rotator portion 41a of the first coupling member 41 is engaged with the hollow 38c of the cord juncture 38. The joint portion 41b is formed to project from the hollow 38c, and has, for example, a male screw 41c, which serves as a joint, threaded on the periphery thereof. The small-diameter portion 42a of the second coupling member 42 has a female screw 42c, which is meshed with the male screw 41c threaded on the joint portion 41b, threaded thereon. The large-diameter portion is a juncture shield 42b engaged with the periphery of the cord juncture 38. The large-diameter portion has a through hole 42d, through which the lock screw 7 is fitted into the screw hole 38d, formed at a predetermined position thereon.
A rotation groove 43 extending circumferentially is bored in the periphery of the rotator portion 41a of the first coupling member 41. The rotation groove 43 enables the universal, cord 4 to rotate substantially 180°C or more relative to the operation unit.
A circumferential groove 41d in which an O ring 44 is fitted in order to maintain watertightness between the hollow of the cord juncture 38 and the periphery of the rotator portion 41a and induce a predetermined magnitude of resistance to a turn is formed on both sides of the rotation groove 43.
A cord member 4b that is an integral part of the universal cord 4 is locked in the hollow of the first coupling member 41, and the anti-break member 6b is mounted on the small-diameter portion 42a of the second coupling member 42 as an integral part thereof.
The male screw 41c threaded on the first coupling member 41 having the cord member 4b locked therein as an integral part thereof and having the O rings 44 fitted in the circumferential grooves 41d is meshed with the female screw 42c threaded on the second coupling member 42 having the anti-break member 6b mounted thereon as an integral part thereof. The coupling fixture 40 attached to one end of the universal cord 4 is thus realized.
Now, how to join the coupling fixture 40 and cord juncture 38 will be described below.
For joining the coupling fixture 40 to the cord juncture 38, first, the rotator portion 41a of the first coupling member 41 is thrust into the hollow 38c of the cord juncture 38 against constraining force exerted by the O rings 44.
Thereafter, the rotation groove 43 bored in the first coupling member 41 is substantially aligned with the screw hole 38d bored in the cord juncture 38 through the through hole 42d bored in the second coupling member 42.
The lock screw 7 is then fitted into the screw hole 38d through the through hole 42d, meshed with the female screw threaded on the wall of the screw hole 38d, and then tightened. The tip of the lock screw 7 is thus put in the rotation groove 43. Consequently, the rotator portion 41a is located at a predetermined position so that it can rotate freely.
Consequently, the second coupling member 42 having the anti-break member 6b mounted thereon as an integral part thereof is rotated. The first coupling member 41 joined to the second coupling member 42 is therefore guided to rotate by an angle determined with the length of the rotation groove 43 owing to the lock screw 7. Thus, the coupling fixture 40 rotates 180°C or more.
Operations to be executed by the endoscope 1 having the foregoing structure will be described below.
To begin with, an operation to be performed when the connector 4a attached to the end of the universal cord 4 extending from the operation unit 3 of the endoscope 1 is mated with a light source connector 5a of the CCU 5 will be described with reference to FIG. 6A and FIG. 6B.
When an attempt is made to connect the endoscope 1 to the CCU 5, the orientation of the connector 4a attached to the universal cord 4 may be reversed as indicated with dashed lines in
In the endoscope 1 of the present embodiment, the second coupling member 42 included in the coupling fixture 40 attached to one end of the universal cord 4 and having the anti-break member 6b mounted thereon as an integral part thereof is rotated 180°C in a direction of arrow B. Consequently, the twist 4c of the universal cord 4 is unraveled as shown in FIG. 6B. The connector 4a can be smoothly mated with the light source connector 5a of the CCU 5.
As mentioned above, the coupling fixture 40 attached to the universal cord is joined to the cord juncture 38 formed on the operation unit so that the coupling fixture can rotate at least 180°C. It will therefore not happen when the connector of the electronic endoscope is mated with the light source connector of the CCU, that the universal cord is twisted to form a twist. This contributes to improvement in the maneuverability of the electronic endoscope.
Next, an operation to be performed when an operator holds the endoscope 1 and inserts the insertion unit 2 into a body cavity will be described with reference to FIG. 7.
When an operator holds the endoscope, the operator's left hand is rested on the part of one flank of the operation unit 3 between the flank and the combination of the cord juncture 38 and coupling fixture 40 attached to one end of the universal cord 4. At this time, when the state of the left hand with which the operation unit is held is changed, the back of the operator's left hand rests against a rigid support structure defined by the combination of the cord juncture 38 and coupling fixture 40. The endoscope 1 is therefore held on a stable basis while being supported at two points, that is, with the palm of the left hand with which the operation unit 3 is held and the back of the left hand resting against the end of the universal cord 4.
With the operation unit held in this say, the distal part 21 of the insertion unit 2 is inserted into a region to be observed at the sight of an endoscopic image displayed on the screen of a monitor that is not shown. At this time, if necessary, an operator twists the insertion unit 2 in a direction of arrow C as shown in FIG. 7.
The cord juncture 38 formed on the operation unit 3 is extended at an acute angle θ with respect to the longitudinal axis of the operation unit 3. The universal cord 4 coupled to the cord juncture 38 with the coupling fixture 40 between them so that the universal cord 4 can rotate freely is extended with the acute angle θ retained with respect to the longitudinal axis of the operation unit 3. Therefore, even when the insertion unit 2 is twisted, the universal cord 4 will not be bent to impose a load on the operation. unit 3 but will move towards the insertion unit 2 as indicated with an arrow D.
In other words, when the insertion unit 2 is twisted, the universal cord 4 merely moves around the insertion unit 2. The endoscope can therefore be manipulated with the operation unit 3 free from any load stemming from the springiness of the universal cord 4.
As mentioned above, the cord juncture to which the coupling fixture attached to one end of the universal cord is joined is formed at the acute angle θ with respect to the longitudinal axis of the operation unit so that the universal cord will extend in a direction substantially corresponding to the direction of extension of the insertion unit (downside in the drawing). A drawback attributable to the fact that when the insertion unit is twisted, a load is imposed on the operation unit because of the springiness of the universal cord can be overcome.
Moreover, the cord juncture is formed at the acute angle θ with respect to the longitudinal axis of the operation unit, and the coupling fixture attached to one end of the universal cord is joined to the cord juncture. When an operator holds the operation unit, the cord juncture and coupling fixture are located near the back of the operator's left hand and serve as a hold assistant. The electronic endoscope can therefore be supported at two points, that is, with the back and palm of the left hand. This contributes to great improvement in the stability of a hold on the electronic endoscope.
Next, an operation to be executed when a treatment appliance is passed through the treatment appliance insertion port 37 interposed between the suction button 32 and aeration/perfusion button 33 will be described with reference to FIG. 8.
When the distal part 21 of the insertion unit 2 of the endoscope 1 is opposed to a region to be observed, an endoscopic image of the region to be observed displayed on the screen of a monitor that is not shown is viewed. A treatment is then performed if necessary. At this time, an operator parts his/her right hand from the insertion unit 2 and passes a treatment appliance 8 through the treatment appliance insertion port 37.
When the treatment appliance has reached a predetermined position, the operator holds the insertion unit 2 with his/her right hand and visualizes the region to be observed on the screen of the monitor.
With the treatment appliance 8 borne with the index and middle fingers of the left hand, the treatment appliance 8 is advanced or withdrawn as indicated with the double-sided arrow in
In other words, an operator can swiftly introduce the treatment appliance 8 to a predetermined position so as to perform a treatment while holding the insertion unit 2 with his/her right hand without the necessity of parting his/her left hand from the operation unit 3. Namely, the operator can swiftly introduce the treatment appliance 8 without disturbing an endoscopic image displayed on the screen of the monitor.
The treatment appliance insertion port through which a treatment appliance is introduced into a body cavity is interposed between the suction button and aeration/perfusion button to be handled with the index and middle fingers respectively. A treatment appliance put into the treatment appliance insertion port can be manipulated with the index and middle fingers without the necessity of changing the positions of the operator's right and left hands. This contributes greatly to improvement in the maneuverability of the endoscope.
Referring to the drawing concerning the present embodiment, the suction button 32, aeration/perfusion button 33, and treatment appliance insertion port 37 are juxtaposed straight on the surface of the operation unit illustrated upside in the drawing. The positional relationship among the suction button 32, aeration/perfusion button 33, and treatment appliance insertion port 37 is determined in consideration of maneuverability. Their location is not limited to the surface of the operation unit illustrated in the drawing, and their layout is not limited to the straight juxtaposition.
Moreover, when it is intended to manipulate the treatment appliance 8, if the endoscope 1 is held with the back of the left hand rested against the hold assistant, the treatment appliance 8 can be manipulated more smoothly.
The first embodiment has been described on the assumption that the endoscope is an electronic endoscope for medical use. The endoscope is not limited to the one for medical use but may be the one for industrial use.
The second embodiment of the present invention will be described with reference to
In the endoscope 1 of the first embodiment, the cord juncture 38 is projected from the middle point of the operation unit 3. In contrast, in an endoscope 1A of the present embodiment, a cord juncture 38a is projected from the proximal end of the operation unit 3 as shown in
A joystick 31A used to angle the bending portion 22 is formed instead of the angling knob 31, which is one of the operation switches, on one flank of the operation unit 3. The other components are identical to those of the first embodiments. The same reference numerals are assigned to the identical components, and the description of the components is omitted.
As mentioned above, the cord juncture to which the coupling fixture attached to one end of the universal cord is joined is projected from the proximal end of the operation unit at an acute angle. Consequently, the insertion unit extending from the operation unit and the universal cord can be balanced easily.
As shown in FIG. 10A and
Moreover, as shown in FIG. 11A and
According to the present invention, it is apparent that a wide range of different embodiments can be constructed based on the invention without a departure from the spirit and scope of the invention. The present invention will be limited by the appended claims but not restricted to any specific embodiment.
